1.springboot添加达梦依赖

 <!--   达梦数据库     -->
        <dependency>
            <groupId>com.dameng</groupId>
            <artifactId>DmJdbcDriver18</artifactId>
            <version>8.1.1.193</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.2.0</version>
        </dependency>		

2.填写配置文件

spring:
  application:
    name: demo-cdd
  datasource:
    driver-class-name: dm.jdbc.driver.DmDriver
    url: jdbc:dm://192.168.xxx.xxx:5236/SYSDBA?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8
    username: SYSDBA
    password: cdd123456

    open-in-view: false
    properties:
      hibernate:
        dialect: org.hibernate.dialect.DmDialect

但是这样配置，数据会在达梦的数据库驱动中强制大写，这对某些接口的数据返回给前端数据大小写出现问题，影响范围较大可以统一将查询操作结果转换成LinkHashMap键值对，再通过BeanMap映射成对应的实体类。具体代码不同情况分开编写，比如clob长文本处理：

                    Object value = map.get(resultkey);
                    if(value instanceof ClobProxyImpl){
                        try {
                            value =  ((ClobProxyImpl) value).getSubString(1,(int)((ClobProxyImpl) value).length());
                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                    }
